A State-of-the-Art of Empirical Literature of Crowdsourcing in Computing

This paper aims at representing a state-of-the-art of crowdsourcing, along with various trends and opportunities of empirical research of crowdsourcing in computing field of study. A systematic mapping study (SMS) methodology has been employed to synthesize the empirical work done in crowdsourcing. This paper is based on the results generated from 400 primary studies of the SMS. The initial results of this SMS suggest that the crowdsourcing in Computing is not a field in its inception phase, rather, this field has matured considerably, with in less than a decade of empirical research. The paper highlights important trends in empirical crowdsourcing research along with gaps and opportunities for the researchers.
